Add distribution package for managing pulls and pushes. This is based on
the old code in the graph package, with major changes to work with the
new image/layer model.
Add v1 migration code.
Update registry, api/*, and daemon packages to use the reference
package's types where applicable.
Update daemon package to use image/layer/tag stores instead of the graph
package

The image store abstracts image handling. It keeps track of the
available images, and makes it possible to delete existing images or
register new ones. The image store holds references to the underlying
layers for each image.
The image/v1 package provides compatibility functions for interoperating
with older (non-content-addressable) image structures.

The tag store associates tags and digests with image IDs. This
functionality used to be part of graph package. This commit splits it
off into a self-contained package with a simple interface.

Layer store manages read-only and read-write layers on a union file system.
Read only layers are always referenced by content addresses.
Read-write layer identifiers are handled by the caller but upon registering
its difference, the committed read-only layer will be referenced by content
hash.

Can't safely use uint32 for locker since we need to decrement the count,
which requires loading the unit and doing some math, which is inherintly
racey.
Instead use Int32 which we can safely use with atomic and AddInt32 with
`-1`

Add a flag to allow keeping bundles around (helps with CI)
Fix several problems in repo make targets
* quote DOCKER_EXPERIMENTAL variable
* pass-through arguments for gpg provided to dpkg-sig are now quoted
properly, so passphrases with shell-interpolated symbols can be used
* when determining deb suites, don't rely on 'origin' to be
github.com/docker/docker
Fix some issues with deb repository creation from scratch
* Don't add empty components to the repository configuration as they
will cause failure when generating.
Add old docker-engine-cs name to package conflicts
